Contract or Pay as you go on iphone?

So I'm thinking of getting an iphone 4s, but I don't know whether I should get contract or pay as you go. I wouldn't make many calls, but quite a few texts per month, and I would need to use the internet outside of a Wi-Fi connection zone. Could anyone give me the cheaper option, and then the option that would most fulfil my requested needs? And could anyone tell me if you can get iphone 4s contracts for less that £20 per month? And if you can't get it for under £20, then what is the best deal? As you can probably tell, I don't know much about phones, so you'll have to speak quite plainly.

Try the company 'Three'. If you have a number already it's easily transferable. Pay As You Go iPhone 4S will set you back some money but a contract with Three is £23 a month with Unlimited Texts and Data but only 100 minutes of calls. Or if you go for the Pay As You Go option it, find a cheaper cost for the iPhone elsewhere and get a Sim Only deal which will knock you back around £10-£17 a month for unlimited everything.

If you are not going to use it often then pay as you go will do.

I deffinitly think that you should get a contract. I think you can get an iphone 4s from tesco mobile for about 20 pounds per month. It would be most cost effective because if you think about it.around 12 p per text. If you use internet when you're not on Wi-Fi then it will cost you loads on pay as you go. So yeah, you should probably get contract if its in your budget. Hope i helped.
